Abstract

The invention discloses a method for enzymolysis treatment of oil crop seeds. The method comprises the following steps that 1, oil crop seeds are contained in a closed container and subjected to the humidification and pressurization conditions for 10-15 min, then, pressure is decreased to 1500-2000 Pa, the pressure is maintained for 10-20 min, then, the pressure is increased to 1.6-2.5*10<5>pa, and the pressure is maintained for 20-30 min; 2, the oil crop seeds are smashed, and water is added into the smashed oil crop seeds; 3, firstly, oil crop seed granules are baked, and then subjected to microwave processing; 4, the temperature of the oil crop seed granules is decreased to be 20 DEG C to below, then, cellulase and compound protease are added into the oil crop seed granules, enzymolysis is performed under the temperature of 40-45 DEG C for 5-8 h, and finally the enzymolyzed oil crop seed granules are subjected to low-temperature vacuum drying to obtain oil crop seeds for cold pressing method extraction.

Description

technical field [0001] The invention relates to a method for enzymatically treating oil crop seeds. Background technique [0002] At present, the commonly used vegetable oil extraction methods are mainly pressing method and leaching method. Among them, the leaching method has more solvent residues and the oil quality is lowered, while the pressing method is simple and safe to operate, but the residual oil rate of the cake is high. Pressing methods include hot pressing and cold pressing, and cold pressing is a process for producing oil. The cold pressing method retains the most complete nutrients. Because the oil yield of cold pressing is only half of that of hot pressing, the price of most cold pressing oils is about 50% higher than that of hot pressing. Because the cold-pressed oil is not damaged, it generally does not need to add additives, and it can be stored for a long time. The market value is relatively high-end. However, compared with hot pressing, the oil yield ...
